The gastrointestinal distress felt as a consequence of eating at the cultural phenomenon known as Denny's. A combination of The Itis and The Shits, Shitis takes effect the instant the Denny's waitress brings your check. Early symptoms include nausea, bloating, lethargy and a sense of extreme drowsiness.
In the later stages, those affected will experience bloating, smelly gas, and explosive greasy leakage from the anus, too horrible to be considered an average case of diarrhea.
The only effective treatment for The Shitis is to build up a tolerance for food considered unsafe for human consumption. This can be accomplished by regularly consuming Fried Cheese Melts at Denny's topped with bacon, and a side of fries.
I was about to get some after taking my girl out to Denny's, but I developed The Shitis during foreplay and made a mess. At least it was in her bed and not mine.
Chicago term. It means the opposite of lacking. To be "with the shits" means to be in direct possession of enough of physical protection for the amount of illegal merchandise (work) you are currently attempting to move. On the South Side of Chicago, holding any amount of work requires at least a sidearm; larger amounts of work call for additional crew members and more guns. If another crew is able to take your merchandise by force then you are lacking and are not at all with the shits. Popularized by many Chicago rappers, perhaps most notably by Fredo Santana on his track "My Lil Niggaz".
Outside of Chicago, the term has loosely come to mean simply a willingness to engage the types of illegal activities commonly discussed in popular hip hop music. If you're actually in Chicago, however, it's important that the original definition be observed at all times. You absolutely do not want to get caught lacking in the field.
